英文摘要	A two-dimensional axisymmetric model of free burning tangsten inert gas (TIG) arc under the action of pulsed current is developed. Using the FLUENT software and choosing appropriate boundary conditions and strongly coupling control equations, a pulsed TIG arc is simulated. The variations of arc form, temperature field, temperature and velocity on the arc axis and surface pressure distribution of the workpiece are obtained and analyzed in the periodic current process; under the action of different values of peak current, duty ratio and pulse frequency, the arc pressure distributions are obtained and analyzed. The results show that they lag behind the variation of pulse current, the variation from base current to peak current is faster, then eventually reaches a relativly stable state; with the increase of peak current, the arc pressure increase greatly; with the increase of duty ratio, the arc pressure increases slowly; with the increase of pulse frequency, the arc pressure cannot reach a stable state gradually, and the max arc pressure tends to decrease.
